A Study on Video Steganographic Techniquesijceronline
Data hiding techniques have taken important role with the rapid growth of intensive transfer of multimedia content and secret communications. The method of Steganography is used to share the data secretly and securely. It is the science of embedding secret information into the cover media with the modification to the cover image, which cannot be easily identified by human eyes. Steganography algorithms can be applied in audio, video and image file. Hiding secret information in video file is known as video steganography. Video Steganography means hiding a secret message that can be either a secret text message or an image within a larger one in such a way that just by looking at it, an unwanted person cannot detect the presence of any hidden message. For hiding secret information in the video, there are many Steganography techniques which are further explained in this paper along with some of the research works done in some fields under video steganography by some authors.

Comparative Study on Watermarking & Image Encryption for Secure CommunicationIJTET Journal
Over the past decades, research in security has concentrated on the development of algorithms and protocols for authentication, encryption and integrity of data. Despite tremendous advances, several security problems still afflict system’s. In this android app watermarking and encryption is being applied on images and data. Because of the human visual system’s low sensitivity to small changes and the high flexibility of digital media, anyone can easily make small changes in digital data with low perceptibility. Here watermarking and encryption are being performed in wavelet domain. Here in watermarking, the coefficients of watermarks are being embedded with the coefficients of the original image. Encryption is being done in wavelet domain so that the probability of an intruder trying to access the contents is very much minimized. Thus, this model provides a high level of security.

Design and Implementation of Lifting Based Wavelet and Adaptive LSB Steganogr...Dr. Amarjeet Singh
Image steganography is an art of hiding images
secretly within another image. There are several ways of
performing image steganography; one among them is the
spatial approach. The most popular spatial domain approach
of image steganography is the Least Significant Bit (LSB)
method, which hides the secret image pixel information in the
LSB of the cover image pixel information. In this paper a
LSB based steganography approach is used to design
hardware architecture for the Image steganography. The
Discrete Wavelet Transform (DWT) is used here to transform
the cover image into higher and lower wavelet coefficients
and use these coefficients in hiding the secret image. the
design also includes encryption of secret image data, to
provide a higher level of security to the secret image. The
steganography system involving the stegno module and a
decode module is designed here. The design was simulated,
synthesized and implemented on Artix -7 FPGA. The
operation hiding and retrieving images was successfully
verified through simulations.

Steganography is a technique of concealing the secret information in a digital carrier media, so that only
the authorized recipient can detect the presence of secret information. In this paper, we propose a spatial
domain steganography method for embedding secret information on conditional basis using 1-Bit of Most
Significant Bit (MSB). The cover image is decomposed into blocks of 8*8 matrix size. The first block of
cover image is embedded with 8 bits of upper bound and lower bound values required for retrieving
payload at the destination. The mean of median values and difference between consecutive pixels of each
8*8 block of cover image is determined to embed payload in 3 bits of Least Significant Bit (LSB) and 1 bit
of MSB based on prefixed conditions. It is observed that the capacity and security is improved compared to
the existing methods with reasonable PSNR.
encryption based lsb steganography technique for digital images and text dataINFOGAIN PUBLICATION
Digital steganography is the art and science of hiding communications; a steganographic system thus embeds secret data in public cover media so as not to arouse an eavesdropper’s suspicion. A steganographic system has two main aspects: steganographic capacity and imperceptibility. However, these two characteristics are at odds with each other. Furthermore, it is quite difficult to increase the steganographic capacity and simultaneously maintain the imperceptibility of a steganographic system. Additionally, there are still very limited methods of Steganography to be used with communication protocols, which represent unconventional but promising Steganography mediums. Digital image Steganography, as a method of secret communication, aims to convey a large amount of secret data, relatively to the size of cover image, between communicating parties. Additionally, it aims to avoid the suspicion of non-communicating parties to this kind of communication. Thus, this research addresses and proposes some methods to improve these fundamental aspects of digital image Steganography. Hence, some characteristics and properties of digital images have been employed to increase the steganographic capacity and enhance the stego image quality (imperceptibility). Here, the research aim is identified based on the established definition of the research problem and motivations. Unlike encryption, Steganography hides the very existence of secret information rather than hiding its meaning only. Image based Steganography is the most common system used since digital images are widely used over the Internet and Web. However, the capacity is mostly limited and restricted by the size of cover images. In addition, there is a tradeoff between both steganographic capacity and stego image quality. Therefore, increasing steganographic capacity and enhancing stego image quality are still challenges, and this is exactly our research main aim. To get a high steganographic capacity, novel Steganography methods were proposed. The first method was based on using 8x8 non-overlapping blocks and quantization table for DCT with compression. Second method incorporates the DWT technique, with quality of any stego images as enhanced to get correct hidden image. And last LSB as to store images with Key type security built in.

Design and Implementation of Data Hiding Technique by Using MPEG Video with C...Editor IJMTER
This paper proposes a technique on data hiding approaches using compressed MPEG video files.
This approach hides the message bits by modulating the quantization scale of constant bit rate MPEG
videos. Payload is calculated for each macroblock and proposes to achieve one message bit per
macroblock. Macroblock level feature variables are calculated.To find the association between
macroblock level feature variables and value of a hidden message bit, a Second Order Multivariate
regression model is used. To achieve the very high prediction accuracy, the regression model is used by
the decoder. To decode the message, a feature variable of MBs from the encoded bit stream are computed
by the decoder and expands them to the second order and uses the model weights to predict the message
bits. This solution provides very high precision accuracy in predicting the message bits . The proposed
technique is analyzed in term of quality distortion, excessive bit rate, message pay load and message
extraction accuracy. The proposed solution is better in terms of message payload while causing the less
distortion and reduced compression overheads compare to the previous works.

This survey propose a Novel Joint Data-Hiding and
Compression Scheme (JDHC) for digital images using side match
vector quantization (SMVQ) and image in painting. In this
JDHC scheme image compression and data hiding scheme are
combined into a single module. On the client side, the data should
be hided and compressed in sub codebook such that remaining

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
